I have searched and found many possible solutions, but I have not gotten any of them to work. I need to pull down an XML and save it to disc and then recall it and pull an elements value from it. I have successfully saved the XML to disc, but now I can't get the value from the single element. I found a bunch of loops and arrays to get all the data in different forums but I seem to be failing.
Any help would be appreciated, and I know I have a bunch of extra and repeating imports, it is just mess from trying so many things. Thanks!!!
The XML:
<?xml version="1.0" encoding="UTF-8" standalone="no"?> <licenseActivated> <licenseKey>654</licenseKey> <expirationDate>10/31/2016</expirationDate> <uniqueId>Unique ID</uniqueId> </licenseActivated>// // Sample License App for COMP394 // // Import statements import java.util.Scanner; import java.io.BufferedReader; import java.io.DataOutputStream; import java.io.InputStreamReader; import java.io.*; import java.net.HttpURLConnection; import java.net.URL; import javax.net.ssl.HttpsURLConnection; import javax.xml.parsers.DocumentBuilder; import javax.xml.parsers.DocumentBuilderFactory; import java.net.URLConnection; import java.io.InputStream; import org.w3c.dom.Document; import org.w3c.dom.NodeList; import org.w3c.dom.Element; import org.w3c.dom.NodeList; import org.w3c.dom.Node; import org.w3c.dom.Document; import org.w3c.dom.NamedNodeMap; import javax.xml.xpath.*; import org.xml.sax.InputSource; import javax.xml.transform.*; import javax.xml.transform.stream.StreamResult; import javax.xml.transform.dom.DOMSource; import javax.xml.xpath.XPath; import javax.xml.xpath.XPathFactory; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.parsers.DocumentBuilder; import org.xml.sax.SAXException; import org.xml.sax.SAXParseException; import javax.xml.xpath.XPath; import javax.xml.xpath.XPathConstants; import javax.xml.xpath.XPathFactory; class LicenseApp { public static void main(String[] args) { LicenseApp http = new LicenseApp(); System.out.println("Key Verifyication!!!"); http.sendkey(); //while( http.validation2() == false) //{ //System.out.println("Key is wrong"); //} //System.out.println("Confgrats, the key is good!!! \nContinue with your program!!!"); } private boolean sendkey() { Scanner user_input = new Scanner(System.in); String key; System.out.println("Please enter your key."); // Outputs the prompt for information key = user_input.next( ); boolean valid = false; DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance(); try { String urlString = "http://localhost/license_response.php?response=activate&license=" + key; URL url = new URL(urlString); URLConnection conn = url.openConnection(); DocumentBuilderFactory factory2 = DocumentBuilderFactory.newInstance(); DocumentBuilder builder = factory2.newDocumentBuilder(); Document doc = builder.parse(conn.getInputStream()); // doc.getDocumentElement().normalize(); TransformerFactory factory3 = TransformerFactory.newInstance(); Transformer xform = factory3.newTransformer(); //xform.transform(new DOMSource(doc), new StreamResult(System.out)); // Outputs to screen DOMSource source = new DOMSource(doc); StreamResult output = new StreamResult(new File("C:\\school\\COMP394\\Project\\Java.Program\\license.xml")); xform.transform(source, output); // Saves to file } catch(Exception e) { } return valid; // Return boolean value } }
